Dominance relationships in a group of domestic dogs (Canis lupus familiaris)
We investigated the extent to which dominance relationships, as described for feral dogs and wolves, applied to a group of 24 neutered companion dogs at a dog daycare facility. Similar to otherExpand
Conflict management in wild spider monkeys (Ateles geoffroyi yucatanensis)

Owner attention facilitates social play in dog-dog dyads (Canis lupus familiaris): evidence for an interspecific audience effect.
The availability of caretaker attention may be a proximate explanation for social play in canids that have ontogenetically rich histories with humans and also retain neotonized behavior as adults. Expand
